to all whom it may conrern:

lie it tmowu that urol vounly ot' fian l raiu-iero amt State oi: talit'tunla. have IIIYtIllttl neu and usetul Improvements in ilutomohih ltailiator of 5 uhirh the following is a speritieatiou 'l'hiu lllttlltlhll relates to radiat rs, and

partiruhu'ly to radiators wed in con- (culling their parts.

The ohjeet o! the present invent on n to inrreaw the rooting etlieieney ot l'tl llttllitht and to provide simple, effective radiators adaptable to a variety ot' worklng (()llllttions'.

lt la a deoidel'atm'n to provide whereby the eooling tluid from the enginw un he quirltly I't'tlllt't'tl in temperature and to prevent through the radia r toward the eugiutatlum av iding the ptl tl)lllt ot' eonveyiug' grit. ilu t or other foreign material toward the nothing! parlu oi the engine,

The intention eonsisto ot the the llwlllhtltlll and eouihiuatiou hereinafter parts and of parts, more full ilesrriherl and laiou-d, having ret'ereucm to the areompany inn drawings. in whirle- Figure l is a front View of the radiator Fig, 2 is a ventral vertieal trausrerm ((f tion of the some.

lo aeeompli hiug the objeete of my inven tion I may mnploy a radiator A of any pret'errml style or form. having at its upper portion the water heart 2 and at itu lower port ion the water ehamher 3, to the upper ol' whieh heated water is rouveyed through :1 pipe 4 from an engine. not ,ueeessary to he vshown. and from the uppet water hero! 3 the heated water pa se= rlmvuwardly thrmmgh a s rieo of water tubes or (Ulltltlt'tlllh 5 whirl may he of any design. and hetween whirh there are formed pasuages 6 through which air may flow in a general downward rertieal course to the bottom water (than:- her 3.

In order to insure the general vertical flow of air through the radiator. I fix upon the front thereof. a removable plate 7 by suitable fastening devices 8 He cured thereon. and which project transversely through the radiator and through a remoialole hark plate 9 whieh will be seeured against the rear surt'aee of the radiator by the nuts '10 screwed on the bolts 8.

downward jttlitllflll with CHQ'HHH employing water for i a radiator l, JAHEN ll. (tannin riiimu ot' l uited Stabreouluu: H] the ml outliriently below extends from the bottom upwardly and terminates the water head 2 to form an opening 11 whereby a suttlcient volume of air may flow into the radiator between the reveral water tubes or eouduetors 5. Air \rhieh tlow in through the opening 11 is .lh-lleeteil downwardly by meam of a reiuorahle detleetor or sectirmal plate 12 whieh is in area approximately equal to the area of the air opening 11, and whieh in removahly uerured to the rear of the radiator by suitable, loelcing devices, as bolts 13.

When this radiator is used in combina tion \\ith a motor vehicle and the latter is driven, a natural draft is caused to flow into the opening 11 above the front plate 7 by the pressure (it the at against the radiator. This draft of air ill [low downwardly between the eonduet'ors 5. and front and haek plate; 7 and and may flow through verilt'tll IHIHHIIQTWVHNYH 14 tormed through the lower water ehaulber i5 and into a eommon tlis-eharge casing 15. or it may flow forwardly or rearwartlly into a euitahle housingit illt'll may be attached to the radiator. v

In eertain cases it is desirable to aceelerate the low of air vertically through the iorlowd radiator, as by means of a suitable merhanical deriee, here represented as a blower 1?. mounted upon a shaft 18 supported upon or adjaeent the radiator. While in operation the blower exhausts the air from the lHHlHllig and diueharges it, as at l9. Thi blower may be ofany tie and eharaeter and may be driven by any xtlltillllt SOXII'IP of power and may be mounted rlireetly upon an engine or other shaft, it being understood that the purpoae of eupplying the blower IT is to eauoe an induced draft of greater velocity through the closed radiator. and any form of blower mounted in a eouvenient position will beetl'eetive t0 :u-eomplish this result.

A plu ality of the passageways 14 may be provided in the lower Water ChaIflbQl 3, as shown in Fig. 1, and air flowing vertically downward through the radiator may pass through these passageways 14: or, if desired these passageways may be closed and all of the air eaused to How forwardly or ream-unity through the housing 16 which rouuumoeates with the housing 15 from The Front plate T of the radiator which the air passes to the blower '17 wheresion may be madefor the incoming of a large volume of air at greater speed by a swinging plate '20, which is pivoted at 21 upon the back radiator plate 9, and when the pressure of air in the radiator between the plates 7 and l is sufficiently great the Swinging plate 20 may freely open to allow a portion of the air to flow outwardly and downwardly through a rear housing, 22 at tached to the radiator.

By my form of construction the air, whirh passes inwardly through the opening ll above the front plate 7 of the radiator, is led downwardly and vertically between the fluid conduits 5 beginning at their uppermost'portion where they have the greatest. temperature and flowing downwardly of fectively cooling the water in the conductors, the air being finally disclnirged from the housing 15.

In rvrtain rlimal'es it may he desirable to prevent the admission of very rold air at the front of the radiator above llu plate 7. in which event the rvnuwable uction or plate 12 may he unr'ouplod from the rear of the radiator and vahifl'ed to the front thereof so a; to clone the opening 11. This will then produce an opening at the roar of the radiator at the position or-oupied by the plate l2 in Fig. 2. Thus (the air which would be drawn into the radiator would he of H()ll'l(.\"l1ll higher tflllllulflllll? than that at the 'front of the radiator which is generally suhjerted directly to the amine phi-re and pressure of the air wlun the Mr dlalor is mounted upon a motor vehicle.

lt will he understood that. if desired, the air may he taken into the radiator through its vertical legs 23 by forming a 'ipropriate opening at their upper portion adpirent. the water head Q'whou the desired rooling oll'rot would be produred by leading; the in coming air vrrtioally dmvnwardly through the radiator.

In operation when the radiator is being moved lOI'WfHl'L an when mounted upon a.

motor vehicle or when the bloom l? is hm the air so drawn in through the opening ll is rendered tl'erlivo in the radiator the air finally dier'hargod From the hoiramg 17.

The partirular feature of this inrontion is j in the diatrihution ol the air through llu' radiator hetwevntho front. and ark nlalw 7 and whlolrare semi-rd to the radiator. against the conductors 5.

if desired. suitable dellortors an El not in iusorlrd to distriliuto the tlow of air through the radiator.
